As the airfoil section of fan blade design is diversified and complex,
traditionally it took a long period of time to complete the 3D modeling
for fan blades. However, with the powerful surface design features and
associativity of Pro/ENGINEER, the system can automatically generate
each section according to relevant parameters, and update calculation
modules and 3D modeling accordingly. In addition, by allowing different
types of data import, Pro/ENGINEER also supports seamless integration
with TWPB’s analysis software. With the software and service support
from PTC and its channel partner Beijing Link-on Technology Co., Ltd.,
TWPB has as a result improved its product data accuracy and design
efficiency.

“PTC’s 3D, parametric CAD software, Pro/ENGINEER has greatly reduced our
workload and shortened new product development time and cost. We are
very satisfied with the pre-sale and after sale services and training
provided by Beijing Link-on Technology,” said Nie Yongjun, Vice General
Manager of Baoding Tianwei Wind Power Blade Co., Ltd. “We look forward
to working with PTC and Beijing Link-on Technology to deploy additional
PTC solid modeling technologies and relevant solutions.”

The global energy shortage has brought unprecedented opportunities for
the development of new types of energy, and as a result, China's wind
power industry is expected to see tremendous growth in the next few
years. In 2007, the number of new wind power units globally increased
32.1%, amounting to the capacity of 20.073 million kilowatts. In China,
the number climbed by 121% to 2.96 million kilowatts and the total
capacity reached 5.56 million kilowatts, an increase of 114%, the
highest growth rate in the world. The number of Chinese wind power
equipment manufacturers has increased from half a dozen to more than 50
in the past five years. In addition, the Chinese government has attached
great importance to the issue with a number of energy-saving, emission
reduction and new energy policies.

“We are very pleased that TWPB has selected PTC's product, Pro/ENGINEER,
as its powerful design features will help TWPB design team to improve
product 3D modeling efficiencies, ensure product quality and reduce
production time,” said Sin Min Yap, director, product and market
strategy, PTC. “PTC is committed to help enterprises such as TWPB use
Pro/ENGINEER to achieve their product development objectives and
maximize their ROI.”
